Dennerle Crystal Quartz aquarium gravel has a grain size of 1–2 mm and rounded edges, which reduce the risk of injury to bottom-dwelling fish. It is suitable for plants with delicate roots, while the small gaps between the grains provide space for beneficial bacteria to colonize.
It contains no hardening agents, does not harden the water, and is resistant to light and CO2. No pre-washing is required, and it can be reused while retaining its color.
